Besides being a point of light, a star is a luminous, spherical mass of plasma, enough to hold itself together under its own gravity. On its own, though, gravitational rounding isn't enough. What ...

The discovery of the universe’s oldest stars, identified within our own Milky Way galaxy, marks a significant leap forward in our understanding of cosmic history. These ancient stars, formed shortly ...

Theorists have long wondered how massive stars–up to 120 times the mass of the Sun–can form without blowing away the clouds of gas and dust that feed their growth. But the problem turns out to be less ...

Pictures are the key to new insights in the field of astrophysics. Such images include simulations of cosmic events, which astrophysicists at UZH use to investigate how stars, planets and galaxies ...

Astronomers have captured the clearest picture yet of how massive stars are born, revealing a dramatic interplay between gravity and magnetic fields in some of our galaxy's most dynamic star forming ...

Stars usually form in clusters, which can also form in pairs or groups. Binary clusters (BCs) are defined as pairs of open clusters closely associated both in position and kinematics. They provide ...

Scientists traced star-forming gas clouds in a nearby lenticular galaxy, NGC 1387, offering new insight into early-type ...

Alexey A Petrov receives funding from the US Department of Energy. Scientists working with the James Webb Space Telescope discovered three unusual astronomical objects in early 2025, which may be ...
